I wanted to know if anyone knows the market value on a Konica Instant Press camera. I want to purchase one of these but have no idea what the right price is. Thanks in advance for any help. Any advice is appreciated.

Yeah, he is right. This camera is very rare and very good. I think one of the most rare instant cameras on the market. If it is in good working condition you should get much more than 300 US dollars for it. I was looking for this camera a long time ago. I saw this camera only two times on ebay. Very professional camera with complete manual control and flash connector. Lucky guy......
Kind regards from Hamburg (Germany).
